7. Optimization & Troubleshooting
After original setup is complete, you may wish to maximize performance by first optimizing the Airlink
(or RF link) and then optimizing the HiPR-900 radio modem to function in the resulting environment. A
useful RF link diagnostic tool is the built-in Spectrum Analyzer that continually monitors signal strength
with each packet during normal operation.

Spectrum Display

Prior to using the spectrum display for diagnostic evaluation, ensure the system is in-sync and receiving
enough payload data to fill the display.
Note:
If existing traffic data is insufficient, at least two continuous pings of 1400 bytes (use multiple
command prompt windows) to any remote Ethernet IP address accessed across the airlink will
suffice to fill the display.
As the display incorporates significant averaging, changes in the signals may take from 10 to 30 seconds
to be visible.
